Adding custom groups to CP group chat.

Well, I own a Darkrp server and have recently added some custom classes for donators. Now these classes are a part of the CP or Police faction.

I have tried almost everything to get them into the same /g group chat as the default CP classes. Can anyone help?


Posting what you have would be a good start.

I have a S.W.A.T. Custom class, and I have a CP supplier.
